GARBURETER FOR ExFLOSIVE-ENGINES.

Specification of Letters Patent.

Patented March s, 1908.

Application filed June 1. 1906- Serial No. 319.768.

To all whom it may concern: Be it known that I, EMANUEL JOHN BoY- LER, of the city of Peterborough, in the county of Peterborough and Province of Ontario, Canada, have invented certain new and 'useful Improvements in Carbureters for Explosive-Engines; and I hereby declare that the following is a full, clear, and exact descri tion of the same.

is invention relates to a carbureter for an explosive engine, comprising a m xing chamber, having a fuel inlet and an air inlet, an atomizer op osed to the fuel 1n1et and a valve controlled as outlet, and an injector comprising a va ve controlled fuel chamber to be connected with the fuel supply, a sucker to create a partial vacuum in t e fuel chamber, an outlet from the fuel chamber to the mixing chamber and a spring actuated valve to control the fuel outlet, as herelnafter described and specifically pointed out In the appended claims.

For a full understanding of the invention referenceis to be had to the following description'and to the accompanying drawings .in which Figure 1 is a longitudinal section of an explo'sive engine with the carbureter attached thereto, and Fig. 2 is a section of the carbureter on a larger scale than in Fig. 1.

Like characters of reference refer to like parts throughout the specification and drawin s.

The mixing chamber a of the carbureter is provided with a head I) at its outer end through which is formed the air inlets c and the inner end of the mixing chamber a is screw threaded. Formed through the cylinder casing e is a screw threadec a erture d to receive the screw threaded end 0 the mixing chamber a. Formed through the side of the mixing chamber a is the fuel inlet f and contained within the mixing chamber is an atomizer g opposed to the fuel inlet f. Closing the iImer end-of the mixing chamber a is a valve h and connected to the valve h is a valve stem '5 which extends through the mixing chamber a and beyond the outer side of injector consists of a fuel chamber m, a fuel screw t inlet 0 to be connected to the fuel supply source a valve seat q inter osed between the fue inlet 0 and the fuel 0 amber and a slideway 1' at right angles to the fuel chamber m and in communication with the latter. Contained within the fuel chamber m is a valve 8 having a valve stem t projecting into the fuel inlet 0 and adjustable on the valve stem t is a nut u. Coiled upon the valve stem t between the nut 10 and the adjacent surface of the valve seat g is a spring 1) which normally holds the valve 8 against the valve seat. Movable in the slideway 1' is a sucker w. The fuel chamber n has an outlet m and controlling the outlet a is a spring actuated valve 'y movable in the valve chamber 2. The valve chamber 2 as shown in the drawing, is located vertically below the fuel chamber m. Fitted on the injector shell at the end of the valve chamber 2 is a cup 0, which receives any leaka e through the plug 1) closing the end of t e valve chamber. The valve is provided with a valve stem 0 movable t rough the plug 6 and coiled on the valve stem 0 between the plug 1) and valve 1; is a s ring d. As shown in the drawing, the suc er w beyond the slideway r is formed with a shoulder e and that portion of the sucker projecting beyond the shoulder e is readed to receive an adjustable nut f. Embracin the sucker w between the shoulder e an nut is the eye 9 of the link h, connected to an movable with the sliding crank i. In the cylinder casing e is a slidewa j in which the sliding crank '2', is longitu inally movable, and fitted on the sliding crank 1', are collars k and Z which engage the outer and inner sides of the cylinder casing to maintain the sliding crank 11 in aposition at substantially right angles to the cylinder casing when moving in the slideway. The sliding crank 'i within the inner face of the cylinder casing e, is formed with eyes m through which is longitudinally-movable the piston bar 0, and adjustable on the piston ar 0 are two nuts p and g. a The piston bar 0 is connected to and'movable with the pistonhead 1".

As shown in Fig. 1, of the drawings, that part of the piston head T which comes into position opposite the valve h has a recess 8 to permit of the o ening movement of the valve h for the a mission of gas from-the mixing chamber into the engine cylinder. The mixing chamber is fitted to the aperture d and the valve it opens from its valve seat t inwardly into the engine cylinder. When the iston head is in the position shown in Fig. 1 of the drawings, gas is admitted from the mixing chamber into the's acebetween the piston heady and cylin er head a. When the gas has been admitted to the engine cylinder, the spring closes the valve h a ainst its valve seat t to prevent theexit of t e gas from the engine cylinder throu the-mixing closing of the valve h thespark from the sparki niter z" explodes the gas to move the piston ead in the direction indicated by arrow in During the outward movement of the piston head the nut the valves and enters the fuel chamber m.

The valve y is at that time ositioned to close the outlet w from the va ve chamber. During the return stroke of the piston head 1" and piston bar the nut 1) comes into contact with the eye m and moves the sliding crank i, in the opposite direction to move the sucker w inwardly in the slideway 1'. The inward movement of the sucker com presses the contents of the fuel chamber 'm to tightly close the valve 8 against its valve seat q and move the valve y to open the out-v let :c from the fuel chamber into the mixing chamber so that when the sucker has completed its stroke, the selected quantity of the fuel will be ejected from the fuel chamber through the outlet a: into the mixing chainber.

To atomize the fuel, the outlet 00 is provided with an atomizer w which breaks up the fuel into fine sprays to effect its ra id vaporization, and the vaporization is furt er accelerated by the contact of the sprays with the atomizer g contained in the mixing chamber. The fuel during its vaporization in the mixing chamber is combined with air admitted through the air inlets c, and while the mixing of the air and fuel is taking place,

thepiston head 1" completes its return stroke by moving in the engine cylinder to the position indicated by the dotted line therein and then commences its outward stroke. When it has attained the position on its outward stroke shown in Fig. 1 of the drawings, it forms a partial vacuum in the engine cylinder and creates a suction which enables the contents of the mixing chamber to force the valge h from its .valve seat and pass into the engine cylinder.

h chamber and coincident with the Fig. 1, and force the piston head tot the outer end of its stroke.

ing into sso,5o2

When the contents of the mixin chamber have passed .into the engine cy' der the spring is automatically 0 es the valve h against its valve seat to prevent the gas returning from the engine cylinder to the mixing c amben When the explosion occurs,

the piston head moves outwardly towards the end of the engine cylinder under the force I of the expansion of the exploded gas, and when it has completed its outward movement it opens the exhaust valve :0 by means of the chain y connectedito the piston head and to the exhaust valve so that during the return movement of the piston head the ex loded gas can be exhausted from the cy ind'er through the exhaust port m. As the piston head completes its return movement, it engages the proection z of the exhaust valve and moves't e exhaust valve against its valve seat a to close the exhaust port 11:". The projection z is adjustably connected to the exhaust valve 0: and the piston head 1* is rovided with an adjustable um ing in b y which the exhaust valve can e cosed at any selected part of the return stroke of the piston head;
